+# to get how to setup build tool.

+# After build tool is downloaded and compiled, a soft symbol linker need to be created

 # Setup the environment for unix-like systems running a bash-like shell.
 # This file must be "sourced" not merely executed. For example: ". edksetup.sh"

 # CYGWIN users: Your path and filename related environment variables should be
